Language and Index Control

Special Word Stems

This section allows managing words where automatic stemming (reducing a word to its root form) causes undesirable effects. This applies particularly to:

• Irregular plurals
• Foreign words
• Brand names

Here, it is possible to:

• Define the correct word stem.
• Prevent a word from being stemmed at all.

---

Examples

Example	Description
	Searching for “Buggys” automatically stems it to “Buggy”.
	Searching for “Slipper” remains unchanged. Without this setting, the algorithm would stem it to “Slip”, which has a completely different meaning.
	Searching for “Balloon” remains unchanged. Without this setting, the algorithm would stem it to “Ball”, which is incorrect.

Tip

By configuring these exceptions, search accuracy is improved, ensuring users find relevant results instead of incorrect matches.

Data Management – Stop Words

Stop words are words (typically filler words) that should be ignored in search queries because they do not help in finding the most relevant products.

These words are:

• Removed from search input before processing.
• Not included in the search index.

---

Example Stop Words

• “also”
• “again”
• “the”

Note

By filtering out stop words, search performance is improved, and results become more accurate.

Data Management – Word List

The word list functions as a dictionary for the respective language.

In German, this is particularly important for correctly splitting compound words during searches.

---

Purpose of the Word List

• Ensures proper word segmentation in search queries.
• Helps recognize compound words in German.
• Allows foreign words to be added when necessary for correct processing.

---

Maintenance

• The word list rarely requires updates.
• Occasionally, foreign words need to be added to ensure correct word splitting.

Note

By maintaining an accurate word list, search accuracy is improved, and unexpected segmentation issues are prevented.

Data Management – SEO Filter List

This function allows generating and exporting a complete list of filters, including their corresponding filter values and URL parameters.

---

Functionality and Contents

• The filter list generation starts automatically when accessing the menu.
• If successful, a confirmation message appears.
• The list can be downloaded via the “Download Filter List” button.

---

Export File Format

• The filter list is exported as a TXT file.
• It contains all available filters and filter values.
• The file includes the following columns:

Column	Description
Filter Name	Internal identifier (ID) of the filter.
Filter Label	Name of the filter as displayed in the shop.
Filter Value	Technical name of the filter value.
Filter Value Label	Name of the filter value as displayed in the shop.
URL Parameter	The URL parameter for the filter and value. Appending this parameter to a URL applies the filter directly.

Tip

This structured export allows for SEO optimization by enabling directly filtered URLs, improving search visibility and navigation.

Data Management – Excluding Categories from the Search Index

This function allows defining categories whose names should not be included in the search index for associated products.

This is useful for broad categories that contain multiple product types, such as “Jewelry & Watches”, which can lead to irrelevant search results.

---

Why Exclude Categories?

If category names are indexed, irrelevant results may appear.

Example Issue

• A user searches for “watches men”.
• The search looks for both words in all indexed categories.
• A “Necklace for Men” in the “Jewelry & Watches” category is found.
• However, a necklace is not a men’s watch, making the result incorrect.

Note

By excluding specific categories, search relevance is improved.

Additionally, category names become a high-value field in the search index. They can be configured with no or only a small penalty during ranking.

---

Configuration

Adding a Category to the Exclusion List

1. Click “Add New Excluded Category”. The category tree opens in a modal.

2. Choose a category using one of two methods:

   • Manual navigation through the tree
   • Search (e.g., searching for “watches” highlights relevant nodes in red)

3. Select a category and click “Add”. Selections must be added individually.

Note

Once configured, the names of these categories will no longer contribute to the search index. This does not exclude the products from search results—only the category name itself is ignored.
